I recently had the VEL Control module replaced as a result of error codes P1092, P1091. I did the VVEL Control Shaft Position Sensor voltage adjustment per manual using Cipher. P Codes are gone and I can drive the car, but now I?m getting error code U1024 and don?t know what is causing it. Can anyone help?

So I just installed the gtm stage IITT kit and Iam getting this code,( U1024,VVEL CAN communication). Has anyone seen or heard of this? I tried clearing the code per sam's request but it wont clear. I have already checked all vacuum lines, and cupplers for leaks...Any ideas?
